Jeff Goldblum's caught in the act with Tim Burton ex/model Lisa Marie (perhaps best known as the sexy killer alien in Mars Attacks!). Click the link below to see a lot more of Goldblum than you're probably ever wanted to see, and just the right amount of Lisa Marie. Water's pretty cold, eh, Jeff?

UPDATE: The naked celebrity supersleuths at Fleshbot say the pics are from 2002, but are just now setting the internet ablaze. So we can't guarantee that Goldblum is still in nudie beach shape.
